VNQ500

Quad channel high-side driver

Features

■CMOS compatible I/O’s ■

Chip Enable

■Junction over temperature protection and diagnostic ■Current limitation ■Shorted load protection ■Undervoltage shutdown

■Protection against loss of ground ■Very low standby current

■

In compliance with the 2002/95/EC european directive

Description

The VNQ500 is a monolithic device designed in STMicroelectronics VIPower M0-3 technology, intended for driving any kind of load with one side connected to ground.

Active current limitation, combined with latched thermal shutdown, protect the device against overload.

In the case of over temperature of one channel the relative I/O pin is pulled down.

The device automatically turns off in the case of ground pin disconnection.

Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality document.
